Fire Weather Planning Forecast for the San Francisco Bay Area and

National Weather Service San Francisco Bay Area
254 PM PDT Sun Aug 31 2025
...ELEVATED FIRE WEATHER THREAT IN THE INTERIOR MOUNTAINS THROUGH
THE LABOR DAY DUE TO LOW RH AND MODERATE AFTERNOON BREEZES...
.DISCUSSION...We remain on the western periphery of a strong high
pressure system. Large scale sinking air, compressional warming
and drying aloft, a strong low level temperature inversion coupled
with diurnal late August solar warming will continue to produce
hot and dry conditions over the interior this afternoon and Labor
Day. Conditions remain cooler along the immediate coast due to a
shallow marine layer and generally light to locally moderate
afternoon sea breezes. Above the shallow marine layer very low
daytime humidities and poor overnight recoveries have persisted
just away from the immediate coast. Winds remain onshore, but
breezy afternoon winds will elevate the fire weather threat in the
interior mountains, especially through favored gaps and passes.
We are closely monitoring an upper low 500 miles southwest of San
Francisco that is forecast to move northeastward and pass across
the district later Monday and Tuesday. Chances are low at the
moment, but if the pattern evolves with improved timing of the
mid-level moisture and best lift associated with the upper level
low we could see isolated convection across portions of the Bay
Area, East Bay Hills and North Bay. Otherwise there`ll be a
deepening of the marine layer with late night and morning spotty
light coastal drizzle possible mid week.
Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
